Various people are reporting about after unlocking his ZTE modem his virtual CD and Micro SD card gets disabled. There is no direct way to enable this. I have already shared a software which was created by MKey team which you can get at here. You can enable or disable your ZTE modem virtual CD-Rom or micro sd card slot.

Command lists for ZTE 3G modems:
